Answer 1

Answer:
`\text{Volume of cone}=(400)/(3)\pi\ ft^3`

Explanation:

Given: Outline of cone with a dotted line rising from middle of base to the point. h = 16 feet

A second dotted line extends horizontally from middle of base to its edge r= 5 feet

We know that the volume of cone is given by :-

`\text{Volume of cone}=(1)/(3)\pi r^2h\\\\\Rightarrow\ \text{Volume of cone}=(1)/(3)\pi(5)^2(16)\\\\\Rightarrow\ \text{Volume of cone}=(1)/(3)\pi(25)(16)\\\\\Rightarrow\ \text{Volume of cone}=(400)/(3)\pi\ ft^3`

Answer 2

Volume of cone = 1/3 x pi x r^2 x h
where r = 5 ft and h = 16ft

Volume = 1/3 x pi x 5^2 x 16 = 400/3 π ft^3
